At present, there are six preparation methods for graphene in the world, micromechanical exfoliation method, redox method, chemical vapor deposition method, orientation epiphysia method, epitaxial growth method, and carbon nanotube cutting method. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

And these methods have some more or less problems and troubles, and Wang Li is not ready to use these methods, of course, his methods are also optimized from these methods.

What he is going to use is a technology that is a future version of the existing technology, the pinnacle of chemical vapor deposition.

Because the best method for preparing graphene at present is chemical vapor deposition, which can prepare a large number of high-quality graphene.

However, this preparation method has some great defects, the requirements for equipment are extremely high, many of the equipment are some foreign equipment that is prohibited from being imported into the country, and there are not necessarily many countries, let alone Wang Li.

Therefore, the domestic preparation method is also in its infancy, and the results are there, but the effect is another matter.

But for this situation, Wang Li is still clear, because those people or countries abroad do not want Huaxia to have such technology, as long as they master this technology and produce it on a large scale, then at that time, this large blank market in China will be his harvesting ground and slaughterhouse!

Graphene, this material, once owned by Huaxia, with Huaxia's manufacturing capacity, if you dare to sell 10 pieces, I will dare to sell 1 piece!

At that time, the global market was not all controlled by Huaxia, so how could you let you destroy the dream of those foreign groups?

They start, limit! Limit! Limit!

Restricting all related technologies and talents from entering Huaxia, a large number of relevant equipment is also restricted from being exported to Huaxia, and even some permitted equipment is sold to companies and research institutes in Huaxia at sky-high prices.

However, chemical vapor deposition, which is now used in countries around the world, is also very expensive and complicated to operate.

However, Wang Li can solve these problems with a method, and the chemical vapor deposition method he has now mastered is the pinnacle name of this method, and Wang Li has also thought about it.

It's called the 10.0 version of the gas method, and almost all the problems that can be thought of now have been solved, and some that can't be solved have also been optimized a lot.

Complex and expensive equipment? I'm sorry, this one is really cheap, it's ten times cheaper than yours.

Complex manual operation?

That No. 1 transferred 100 A-1 manufacturing robots to me, and all the manufacturing steps were entered into the database, which was completely comparable to those mature and experienced workers.

All this is because a special compound liquid works, and this liquid is called graphite water by Wang Li.

In the initial manufacturing process, graphite water is involved in the whole process, and many problems that require special equipment to solve are solved by this graphite.

So now, Wang Li only needs some simple equipment, according to the simplest preliminary steps of chemical vapor deposition, to produce a large number of semi-finished graphene.

The initial experimental equipment was in place, and Wang Li would not have been mass-produced until the effect was seen, and then everything was ready, and Wang Li began the initial experiment.

"Sir, the company's game materials are here."

"Number one, according to the rules I set before, you need to arrange 100 daughter agents to put everything together."

After arranging the game, Wang Li turned his attention back to graphene.

A full set of biochemical protective suits worth more than 100,000 yuan was put on, and Wang Li entered the chemistry laboratory that had been built.

"This graphite liquid is highly toxic to humans, and if I accidentally leak out of the container, I will die without this clothes."

A special test tube in his hand, Wang Li was holding in front of him with some confusing materials.

He carefully picked up a highly corrosive chemical, and then he began a complicated experiment, because it was only a memory in his mind, or some half-finished knowledge, Wang Li's initial experiment was very unsuccessful.

But gradually, he mastered some tricks, and became more familiar with the configuration of graphite water, and this proficiency came up, and what he lacked was constant trying.

...............

A day later, Wang Li walked out of the laboratory with a tired face, although he had not rested for nearly 24 hours, his spirit was still very excited, and he could still see a trace of excitement in his eyes.

"It was a success, and then let the robots try to produce a wave, and the industrial area can start the early manufacturing."

Wang Li held a round glassware in one hand, and inside was a thin layer of black crystals.

"One, according to the operation process I just had, set up a production line with the equipment I ordered earlier, and I hope that when I wake up, I can see the finished product appear."

Wang Li put the graphene in his hand into a special glass case, and then planted it on the bed.

After Wang Li fell asleep, No. 1 began to work, and under its command, the robot began to start some equipment, pouring a large amount of material into the production line, and some barrels of liquid marked with the word danger entered another production line.

These liquids are the raw materials of graphite water, in fact, some of these materials are difficult to obtain, such as the materials for making graphite water, there is a material that is controlled by the state, and Wang Li has to use the power of No. 1 on the network in order to obtain such materials.

It took a lot of time to get some permits, even if it was the number one, Wang Li didn't dare to be careless, who knew what amazing existence was hidden in this world.

Everything went smoothly, Zhang Youming received the news from Wang Li, and immediately ordered the production of other parts of the holographic projection equipment to begin, a production line with sufficient materials was started, and the first batch of graphene chips were also in place.

Because it is the first batch, the experimental nature is still very much, so it is only enough to produce 100,000 large and medium-sized holographic projection equipment, and before the goods are fully produced, Zhang Youming still has one more thing to do, that is, to negotiate with several large domestic cinema companies to use holographic projection.

However, most of Wang Li's current production line are some key parts produced by himself, and these parts have been designed by Wang Li, and the effect has been greatly improved several times, which is not sold by the outside world at all.

Of course, some other parts, such as shells and the like, do not have much technical content, Wang Li is purchased, after all, these things are in large demand, and the production is still very laborious, it is better to buy.
